Hey guys, I've finally got to a point of financial security that I'm seriously considering a transferable, probably something between entry level and "buy once, cry once" such as Mac, AC556, SW76/clones, or an Uzi if an amazing deal pops up. My question is: are there any companies that still offer factory service on machine guns they used to make? I heard Ruger did it for a long time but that they dried up recently. Does Smith and Wesson service their 76s? I'm sure there's some great SOTs that can do it, I'm just curious about how friendly the factory warranties can be.
